Abstract
The present disclosure relates to a system for pressurizing liquid hydrogen (LH2). The system has a pressure vessel for containing an initial quantity of LH2, with the pressure vessel containing an inlet orifice and an outlet orifice. A vaporizer is used which has an inlet and an outlet. A supply tube is used to couple the outlet orifice of the pressure vessel with the inlet of the vaporizer. A discharge tube couples the discharge outlet of the vaporizer with the inlet orifice of the pressure vessel. The vaporizer receives LH2 from the pressure vessel via the supply tube during a pressurization operation, warms the LH2 using an ambient environment, and discharges heated and pressurized H2 back to the pressure vessel through the supply tube.
